(Cl. i- 227) 25 Claims.

This invention relates to printing apparatus, and more particularly to automatic mechanism for printing form letters, circulars and the like, employing therefor continuous web or series connected stat'onery which, after the printing operation. is automatically sub-divided into successive sheets.

The present apparatus is designed for use in mercantile and industrial establishments for rapidly multigraphing letters, bills and circulars, for whfch continuous web printed stationary in roll or packet form shall have been previously prepared, although it may be employed for general type printing of hand bills, circulars and forms.

The web of stationery is preferably pre-printed with a succession of letterheads at spaced intervals, forms or other indicia, in predetermined relation with which successive letter print impressions are to be effected.

A continuously rotating drum carries the printing type, which may be either directly inked or operate through an overlying inked ribbon to effect an impression in a manner sim'lar to the well-known multigraphing machines. While the printing cylinder, of which only a small portion of the periphery may be occupied by printing type, rotates continuously, the paper feeding mechansm is operated intermittently through step-by-stcp movement. the length of the steps being variable in accordance with the size of the desired printed sheet. Paper feeding devices of positive character are employed, which preferablyI though not necessarily, are of the pin wheel type, the pins of which progressively engage in spaced marginal holesrln the paper web. Subsequently to the printing operation the punched margins of the printed web are trimmed off and the web is transversely cut intermediate succeeding impressions into printed sheets.

The object of the invention is to simplify the construction as well as the means and mode of operation of continuous web severing apparatus,

whereby it will not only be cheapened in construction, but will be more efficient in operation, automatic in action, rapid, accurate and uniform in production of printed material, and unlikely to get out of repair.

In some instances it is desired that the final record sheets after separation, be of a size which is not divisible into the periphery of the printing cylinder from which the web has been printed. Sometimes for other reasons the lengths of final separated sheets do not agree exactly with the spacing of successive printed areas on the web, and it is necessary to remove a waste area between successive impressions, and the ilnal individual sheets containing the impressions. In the event of zigzag folded packs wherein it is customary to divide the web or strip on transverse weakened division lines coincident with the folds, it is sometimes desirable to ail'ord clean sharp edges on the severed sheets by cuttng in odset relation at opposite sides of the fold line. This is particularly true when printing checks, drafts or other papers. In either event it is highly desirable that the web or strip be maintained intact until all entries and typed or imprinted inserts have been made. and then the strip severed and the lengths of the severed portions reduced as a nal operation.

Wherefore, the present disclosure ls directed to severing means and the mode of operation for making plural cuts intermediate succeeding imprinted areas.

A further object of the invention is to provide in a web feeding apparatus severing means repetitiously operable at succeeding differently spaced intervals to sever the web or strip into portions of different length.

A further object of the invention is to provide in a web feeding apparatus, severing means for simultaneously severing the web on relatively spaced parallel lines.

A further object of the invention is to provide in a web feeding apparatus timing means for a web severing device by which the severing device is operated in timed sequence to sever from the web succeedng portions of di'erent lengths,

A further object of the invention is to provide in a web severing apparatus having the advantageous structural features and inherent meritorious characteristics and the mode of operation herein set forth.

With the above primary and other incidental objects in view as will more fully appear in the specilcation, the invention consists o! the icatures of construction, the parts and combinations thereof and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

Referring to the accompanying drawings, wherein are shown the preferred but obviously not the only form of embodiment of the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is an enlarged detail sectional view on the longitudinal medial line looking upwardly in tu Fis- .2-

Fig. 4 is a plan view of a fragmentary portion of a continuous record web or strip showing succeeding portions severed therefrom by the presently described apparatus and method.

Fig. 5 is a plan view of an adjustable strip severing portion of a modined apparatus. Y

Fig. 6 is a side elevation of the portion of the apparatus shown in Fig. 5.

Fig. 'I is a detail view of a further modification of the apparatus shown in Figs. 5 and 6 for effecting double cut operation at each actuation.

Like parts are indicated by similar characters of reference throughout the several views.

The apparatus forming the subject matter hereof, as illustrated in the drawings, is mounted upon and between paralel side frames I-I mounted upon a base 2 and interconnected at spaced intervals by suitable tie bars.

The web of continuous series connected stationery is supplied from a roll 3 journaled on the frame I at one end of the apparatus from which the web passes over a guide roll l, thence over a guide table B and between the prlntng cylinder l and a coacting platen 1 having operating contact through a suitable opening in the table.

Beyond the printing cylinder the web passes beneath a signature imprinting roll I. which may, however, be employed for other printing impressions in differently colored ink or in locations upon the web outside the impression area of the printing cylinder 8. Continuing its course over the table l the marginally punched web is engaged by pin wheel feed devices il by which the web is positively advanced through successive movements proportionate to the length of the n'shed sheets, the extent of which is variable at will.

'I'he impression contact ei' the printing area of the rotating cylinder Il with tbe paper .against the platen roll I would ordinarily be sufficient to insure unison travel of separate sheets of paper web when properly fed so long as the impression contact is maintained on a single form. It is desired. however, to advance a paper web drawn from a roll of continuous forms a selected predetermined distance at each operation sufflciently to compensate for the portion of the sheet occupied by the letterhead and a suitable space at the end and preceding the imprinted matter to afford to the printed letter or form a presentabe balanced appearance and uniform length. This feeding motion oi' the paper web therefore varies in extent according with the sise of the ultimate printed sheet. the extent of the letterhead area and that used for balancin-v" the imprint material on the sheet. Any slight differential nr error of the feeding movement which would be cuite unnoticeable on sheets singly fed would be accumulative on continuous web material. and after a few impressions such differential would become cuite serious.

In order to secure accurate registry upon succeeding sheets, it is therefore neeessarv that the advance of the material intermediate ihe impression periods be cuite accurately effected. Hence the use of positive pin wheel feed devices 8 is preferred.

After having served its purpose of accurately and uniformly feeding the paper web, the punched margins thereof are trimmed eff hy being passed under rotary cutters Ill. and finally the printed web. minus its punched margins. is transversely riivded n t regular spaced intervals by a pair of chopuer" type cutters li and il'.

Power is applied through the main drive shaft I2 (beneath the printing cylinder) which carries a gear pinion Il meshing with a corresponding pinion Il upon the platen roll 1. The platen roll pinion meshes with a large gear wheel i5 fixedly connected to the printing cylinder 6 and rotating in unison therewith. The printing cylinder is thus given continuous rotary motion. always in the same direction.

The rotary printing drum is operatively connected through a train of idler gears 3l, IB, 31, ll, 39 and l0 with a gear wheel Il upon a shaft 42 carrying the pin wheel feed devices t to which intermittent motion is thus transmitted. By this means the paper web is advanced uniformly with the rotation of the printing cylinder whle the printing form is in contact therewith, and is further advanced in unison with the rotation of the cylinder either before or after the engagement therewith of the printing form, but such unison movement is not continuous and the paper web comes to rest while the cylinder continues to rotate to present the type form in position for the succeeding printing impression upon the web.

The peripheral pins of the pin wheel feed devices 9 project through registering slots in the feed table 5y into feeding engagement with the marginal holes in the paper web. The feed table is preferably divided and the section contiguous to the pin wheels is pivotally mounted to ailord access to such wheels. The web is maintained in feeding engagement with the pins by an overlying keeper plate 43, which is slotted at Il for the passage of the feeding pins in their rotary travel. The keeper plate Il is carried upon swinging arms Il pivoted at Il, one of which is provided with a peripherally notched head l1 for engagement of a detent It by which the keeper plate is supported in slightly elevated relation above the feeding table D to minimize friction. The pivotal mounting of the keeper plate enables it to be turned to an inoperative position to faclitate insertion and initial adjustment of the paper web upon the pin wheels 0.

Located beyond the feeding wheels B are parallel spaced trimming discs Ill cooperating with a platen roller 50, between which the paper web advances, and by which the punched margins of the web are simultaneously trimmed ofi'. The cutters or trimming discs III are adjustably mounted on swinging arms 5I and adjusted relative to the platen roll by the adjusting screw 52. Idler rollers 4l are mounted adjacent to the trimming discs III and hold the paper web on the platen 50.

Finally the advancing paper web is engaged by a transverse cutter. by which it is divided at spaced intervals into succeeding separate sheets, each of which bears the imprint ot the type or marking devices carried by the printing cylinder in accurately predetermined position upon the sheet. which may also bear a previously printerI letterhead or other data or indicia.

The transverse cutter may be of various forms A quite simple construction consists of a stationary cutter bar Il mounted upon the main frame, with which cooperates sweeps El Vand 54' carrying coacting transverse cutter bars Il and Il. Such sweep arms are adjust-.ably carried upon the revoluble shaft 56 upon which is mounted a driven gear l1, to which motion is transmitted by idler gears 58 and I9 forming a continuation of the gear train operating the pin wheel feed devices. Being operated through the same driving train, the cutters function in timed -retracted by' a asomar relation with the web feeding devices.' Sheets of different length are accommodated by adjusting the 4sweep arms to diterent radial positions about the shaft, thereby changing the timed relation of the cutter knives. In such construction one cutter blade severs the imprinted sheet from the web and the second blade trims the intermediate portion f'rom the advance end of the web.

The preferred formo! cutter comprises a head Bil slidingly mounted upon guide rods 6l supported in a cross bar 62 of the main frame and projecting longitudinally therebeyond. The guide rods are preferably provided with rack teeth B3 for engagement of pinions carried by the head and rotatable by the crank 84 to slidingly adjust the cutter head. Mounted in the cutter head B6 is a vertically sliding knife bar 65 carrying a cutter blade 8l. the cutting edge of which is upturned for cooperation with a second knife 81 stationarily carried upon the head B0. The paper web is progressively advanced between such knives. The sliding knife bar B is normally held spring BB and is guided between the rear `side of the head Bil and an adjustable bearing `or guide plate B9 mounted upon the head. 'I'he movable knife 86 has an upwardly projecting guide or lead finger 1li overlapping the end of the stationary knife 81 to insure proper sliding relation therebetween.

The sliding knife 66 is actuated against the tension of its retracting spring by a pivoted lever plate 1I engaging with a stud 12 on the knife bar B5 and in turn oscillated by a bellcrank lever 13. The bell crank lever is connected bv a link 1I with a rock arm 15 slidinglv adjustable on a rock shaft 1B extending longitudinally of the machine. At its opposite end the rock shaft carries a similar rock arm 11, with a small cam arm 1B, which is engaged by roller studs 18a upon the cam i9' at each rotation of the cam which actuates the gear sector 23, thereby transmitting to the shaft 1B intermittent rocking motion. The shaft and rook arm 15 are splined for relative adjustment longitudinally oi' the shaft in unison with the adjustment of the cutter head 60. as may be necessary to accommodate sheets of different sizes. The links 14 are provided with double pivotal or universal joints to enable them to compensate for rocking motion of the respective connected arms in diiferent planes.

The roller studs 18a being relatively close together, the shaft 1'8 is actuated twice in rapid succession. A second cutting operation is thereby performed on the strip by the blades El in close proximity to the location of the first cut, the strips having 'been advanced intermediate the cutting operations. In such construction. the first cut severs the imprinted sheet from the strip and the second cut severs a relatively small portion intermediate the imprinted sheets from the advance end of the strip.

In lieu of the two roller studs 18a, a single stud may be used. in which case there is added to the cutter head E0 a second pair of cooperating blades 66-B1' which operate in synchronisrn with the blades 66-61 as shown in Fig. 7. This construction enables the strip to be severed at relatively spaced positions simultaneously.

In printing form letters it is quite desirable to imprint a facsimile signature in diiferently colored ink, or it is sometimes desirable for emphasis to print "fill-iris" of different color. For this pur- To pose there is provided an auxiliary printing mechanism.

The continuously rotating cylinder gear i! intermeshes with an idler pinion al transmitting motion to a gear l! upon a transverse shaft il. upon which is mounted for rocking motion an eccentric sleeve 81. Journaled upon the eccentric sleeve I1 is the auxiliary` printing roller l. bearing impression plates or type as may be required. The printing roller is operatively connected with the drive shaft 8B for unison rotation.

The gear train is so proportioned that the printing roller may make several rotations in its inoperative position before being lowered into impression making contact by actuation of the lever 9i and makes but one rotation therein before being returned. The printing roller is supplied with ink from a roller pad 81 by a transfer roller 98 driven through the gear pinions 99-I00 and I 0l from the auxiliary printing roller shaft B6.

In lieu of marginally punched paper as before described, the paper web may be medlally punched at spaced intervals, as shown at H3 in Fig. 4, for engagement of feeding devices.

The use of the present apparatus enables the rapid, accurate and economical production of individual multi-form letters, circulars and other printing operations. By Aemploying stationery pre-printed in roll form, a great saving in material and printing costs is effected. The present apparatus accurately positions its impressions in relation with the severing position and the positive paper feeding means automatically and continuously maintains such relation.

It is to be noted that during successive contact pressure engagements of the strip of material between the imprinting drum 6 and platen roller 1, which ordinarily continues throughoutI a portion only of the rotation of the drum 8, the strip is subject to intermittent frictional feeding impulses. and that the pin wheel 9. located in oil'set relation with the frictional feeding members ii and 1. in the direction of advancement of the strip. maintains continuous feeding engagement with the strip to continue advancement of the strip intermediate succeeding intervals of frictional feeding inuence by the rollers '6 and 1. Thus the intermittent frictional feeding operations of the rollers 6 and 1 alternate with positive pin type feeding operations of the pin wheel 9 which occur independently of the feeding infiuence of the rollers 8 and 1. During a portion of each cycle of operation the strip is subjected to simultaneous frictional and positive pin type feeding operations and during the remainder of the cycle of operation, intermediate succeeding frictional feeding operations, the strip is subject to only positive pin type feeding operation.
